I suggest a strategy to reduce Twitter addiction: limit yourself to following no more than 100 accounts and avoid using the "For You" tab.

A better strategy: just delete your account. I promise you won't miss it after a week.

Delete your account, remove the apps. Block it on the network level if you need to. Just add any friction you can to using it.

If even 1 of those 100 frequently retweets stuff from another 10 accounts, this system stops working.
